I don't see a difference between these two? Both say that you want to have zero or more connections from each item in your model to the items of Standard. And zero or more connections from each Standard-item to items in your model. M2M are done with an intermediate table. But why do you want to add lines in that table that have an entry to your model but no entry for 'Standard'? Its the same as if no entry in the intermediate. I think what django (and south) do is just ignore blank- and null-parameters. Have fun, Arnold
